Description

Cross-domain model multi-party transaction credibility and ledging method

Technical Field

The invention relates to the technical field of block chains, in particular to a cross-domain model multi-party transaction credibility and ledging method.

Background

With the improvement of the technology and the improvement of an informatization system, the production efficiency of data shows the increase of geometric grade, including the basic information, behavior rule information and the like of each element; the rise of big data technology provides technical support for the analysis of mass data and the correlation mining analysis between data, the society enters an era with king data, and big data becomes an indispensable part of social productivity; the big data is used as an intangible asset of individuals, enterprises and governments, is efficiently circulated among the enterprises, the enterprises and all departments of the governments in an invisible form, and plays an important role in social progress and problem solution; however, how the value of big data is quantified and how to perform trusted transactions between two or more parties is a difficult and challenging task.

The data transaction form between individuals and organizations and between organizations is carried out in a knowledge sharing (model cooperation) mode, the problem is that a certain business target of the individuals or the organizations is solved, the used resources are computing resources, data resources and intellectual resources of other individuals or the organizations, and the whole process occurs under an automatic environment; if the resources are regarded as commodities, the knowledge sharing action is regarded as a transaction, and each resource consumption is recorded in a quantitative manner, an intelligent, decentralized and distrusted cross-domain book needs to be established; only in this way, the knowledge can generate value, the sharing of the knowledge is promoted, and then mental sharing economy is formed; the cross-domain model transaction book is specifically applied to various fields:

the requirement of the public security field on cross-domain model transaction accounts is obvious. The public security field is a law enforcement and case handling organization of the country, the regional policy and management are relatively obvious, the computing resources, knowledge resources and data resources of various regions are different, the cross-region and cross-department service collaboration often occurs, the efficiency is low, the value of each party cannot be quantized, and the resource utilization and the service collaboration are seriously hindered; by adopting the cross-domain model transaction book, computing resources, knowledge resources and data resources can be effectively utilized, resource values can be quantitatively recorded, a transparent and credible cooperation environment is established, cross-region and cross-department business cooperation is promoted, and finally contribution is made to public security work and social stability.

The public security and the business cooperation of other social enterprises can also adopt a cross-domain model to trade the account book. At present, various industries and various fields present deep-well development phenomena, which cause the phenomena that various industries sit well and look at the sky, however, the crime criminals' crime means is not limited, but can become criminals to provide opportunities, and cause unstable social factors; if the cross-domain model is used for trading the account book, the digitalized values and contributions of the two parties can be quantized, a credible data trading market is created, business cooperation is promoted, intelligent sharing and data sharing between the public security field and social enterprises, internet enterprises and the like are formed, data resources, computing resources and intelligent resources are effectively utilized, the value of the resources is maximized, and the national security boundary is wider; meanwhile, the public security can also better serve other enterprises in the society, provide excellent environment for the healthy development of the enterprises and form a benign closed loop.

Sharing economy:

the sharing economy is that people fairly enjoy social resources, pay and benefit in different ways and jointly obtain economic dividends

In the future, sharing economy will permeate all areas, and intelligent police affairs will not be exceptional.

(A) characteristics

(1) The communication performance of the network link is the basis of the sharing economy;

(2) credibility, namely the premise of sharing economy by two transaction parties;

(3) informativeness, the sharing of information is a condition for sharing economy;

(4) circulation, the circulation of virtual currency is blood sharing of the economy;

(II) Effect

(1) The share economy expands the trading subject's options and welfare promotion space.

In a traditional business mode, people mainly passively receive commodity information provided by merchants, experience evaluation of individuals on commodities is compressed in a acquaintance circle, and a sharing economic mode based on a network platform enables supply and demand parties to publish shared goods or required goods which can be supplied by the supply and demand parties through the Internet, so that selectable transaction objects of specific supply parties or demand parties are increased, the possibility of mastering more information of the transaction objects is provided, fraudulent unfair transaction and transaction cost are avoided, transaction quality is fundamentally improved, and the increase of welfare of the two parties is facilitated.

(2) Sharing economy changes the concept of property rights of people and fosters cooperative consciousness.

The sharing economy enables more private articles to be shared at a lower price on the basis of not changing all the rights, thereby compressing the relative space of private articles in personal articles and expanding the connotation of the concept of public articles. The development of the collective economy is pregnant in the world, and governments are also required to more widely permeate and intervene in private lives of residents at the national level, so that the transition of social common forms is promoted. By means of the network platform, the user can rent or borrow objects to people who do not know the user, the interpersonal circle shared by the user is fundamentally enlarged, the user can be taught how to share the objects, the life of the user is enriched, and the sharing becomes an important factor which can not be avoided in social interaction.

(3) The sharing economy changes the operating environment of the traditional industry, and forms a new supply mode and transaction relationship. The traditional production mode is that enterprises organize production elements to provide products, the organization degree in the production link is very high, and consumers are mainly scattered customers. The network platform improves the organization degree of consumers, changes the consumption requirements of each customer into more accurate 'flexible production' and 'on-time supply' into a universal production mode, and predicts the arrival of a fine life era. From the perspective of the whole social supply, the share economy reduces the total social supply, promotes the green revolution, possibly starts the next industrial revolution, and becomes the final person of excessive consumption.

(4) Sharing the economy changes the labor relationship.

The sharing economy changes the employment mode of enterprises and the full-time employment mode of labor force, provides a brand-new family planning mode for creative individuals, and people can freely select tasks, working time and salaries which are interesting and adept. In fact, most people who participate in the sharing service have their own jobs, and only view the sharing service as extra income. From the perspective of the company, the mode can ensure that the company can flexibly adjust the scale, the pain of an arbitrator and recruitment is avoided, and the complicated matters such as employee bonuses, insurance, retirement funds, and meetings are not considered. This mode of operation is very beneficial to both individuals and companies, making members of the society a mixture of free-time and part-time employees, making the whole society a contract-wide society.

5. The sharing economy helps to solve government city management problems.

Traffic jam, shortage of ecological resources, contradiction of labor and resources, unfair income distribution and cold desert in neighboring cities are common problems restricting the development of most cities. Under the economic concept of sharing, the local governments can develop wide development cooperation, and the urban and rural gap and the regional unbalance can be reduced by information sharing, policy coordination and human resource sharing among cities. The sharing of bicycles and automobiles changes the policy of cities for improving traffic, the sharing of automobiles can also reduce exhaust emission, the sharing of private residences can also balance supply and demand relations of urban houses, and the sharing of economy can even solve the urban crime problem through stabilizing social networks. The sharing mode is switched into political programs and becomes an important promoting factor of democratized processes. For example, the popular participation budget management in many countries is that all residents of a city or community participate in city budget management together, discuss and decide a common expense project.

(III) sharing the economy in the prospect of intelligent police

In the aspect of public security informatization application, computing resources, a data resource library, a police knowledge library, an expert library and an actual combat model sharing library are used as virtual commodities, a police network is used as a communicated basic environment, fusion of various technical and tactical laws is used as traction, police departments are connected through cross-region police cooperative combat, computing power, network and intelligent resources are quantified into a model account book and recorded, a cross-region model of intelligent police is developed to realize credible and financial transactions in multiple directions, and the final goals of effective resource sharing, circulation and value maximization are promoted.

The prior art has the following defects and shortcomings:

1. the mode of account book record on the market has many, exposes defect and not enough between public security, government organ and enterprise:

2. data transaction lack of trust environment

In the digital era, the demand of individuals and enterprises on data is very vigorous; however, in popular data sharing, a trusted environment is not used for supporting, and data sharing and data circulation are blocked.

3. The traditional accounting mode has poor safety

The traditional data accounting mode is stored in clear text for each user and can be changed at will, and the safety is relatively poor.

4. Poor fault tolerance

The traditional accounting technology has poor fault tolerance, and the whole accounting system is affected by 1 or 2 nodes which are abnormal, so that great economic loss is brought to individuals or organizations.

The required equipment includes: application server and CA authentication server

Specifically, the user CA authentication includes: and providing user registration, user authentication and user logout services, submitting the model transaction to a block chain intelligent contract after the user passes the CA center authentication, confirming the transaction by the block chain intelligent contract and recording the transaction to an account book, and generating a substantial transaction, as shown in figure 3.

(1) User registration

When a user joins the system, the user registers an account number first, the CA authentication center sends a user certificate, and the certificate is used for authentication through the CA center service.

(2) User authentication

After the user generates model transaction operation on the platform, the user certificate is authenticated in the CA authentication center to be a platform legal user, the model transaction is submitted to a block chain intelligent contract, and the model value transaction is formally generated through rules and recorded.

(3) User logout

The user confirms that the logout condition is met, the platform administrator logs out the user, the user certificate is deleted in the CA authentication center, and the platform and the CA authentication center permanently remove the user.

The following explains the intelligent contract:

the smart contract includes a model transaction that defines: model copyright, model sharing, model evolution, model operation, model cloning, image-text viewing and sharing canceling, after the model transaction meets the requirements, the account book is recorded, and the transaction is completed successfully. In the embodiment of the present invention, the model copyright content is: model ID, affiliated unit, creator name, local creation time, release-to-knowledge sharing time, model value, model logic, copyright registration and infringement monitoring.

Smart contracts are an important reason why blockchains are referred to as "decentralized," allowing users to perform traceable, irreversible, and secure transactions without the need for third parties. The smart contract contains all information about the transaction and only after the requirements are met will the resulting operation be performed.

The blockchain intelligence contract defines the uplink value content as shown in table 1.

TABLE 1

The uplink content is named as a model, the integral is quantitative value, model transaction and model operation are circulation modes according to needs, and the operation and use of the platform and the user are added, so that the model is more fresh, activated and valued, the platform content is richer, and the social value is higher; the mode and the cochain content operated by the platform can be finely recorded to form an account book in the block chain, so that the user benefit is ensured, and sustainable development is realized.

Table 2 shows the model transaction types and code values.

TABLE 2

And (3) model copyright: a user creates a cross-domain model on a platform, and a system creates copyright for protecting the user model; the newly-built cross-domain model generates model copyright through a block chain intelligent contract and gives a reward to a user.

Model sharing: the user shares the personal model thought to other users of the platform, in order to guarantee the enthusiasm of user model sharing, the cross-domain model is shared through the block chain intelligent contract recording model, and the user is given credit reward.

And (3) running a model: when the cross-domain model runs, other user intelligence resources, computing resources and data resources are consumed, the cross-domain model runs, computing resources, data resources and intelligence resources provided by other places and cities are recorded through a block chain intelligent contract, and a credit reward is given to a model sharer.

Cloning model: the user can clone the model to the individual account from the platform, and the cloned model user can operate and modify, and simultaneously, the platform records the user clone model through the block chain intelligent contract, and gives the model sharing the credit reward.

And (3) checking image-text details: a user can check the image-text details, learn model ideas and description documents on the platform; meanwhile, the platform records the user viewing image-text details through a block chain intelligent contract, and gives the model sharing point reward.

And (3) cancelling the sharing model: the user has the right to cancel the sharing model, and other users cannot see the model in the platform after cancellation; meanwhile, the platform records that the user cancels the sharing model through a block chain intelligent contract, and gives a reward to the user who cancels the sharing model.

Then, the intelligent contracting party can confirm the transaction and record the transaction to the ledger through the block chain, and the substantial transaction is generated.

The model transaction operation is communicated with the intelligent contract of the block chain through a rest interface, and the json data format is as follows

Here, model transaction data sets are represented, each model transaction data set being in { }, and the format of each model transaction data set being standard and fixed.

tasKID, a unique identifier representing the model transaction ID and each transaction record

details representing contents of model transaction type, values corresponding to contents defined by transaction type

The operateClass indicates the transaction type, and the transaction types are various and have different codes so as to confirm the transaction type by the codes

OperateHash, which represents the transaction number and the service flow number of the transaction

Representing account owner, platform user account number

points, expressing points, the value points of the transaction

txHash represents the transaction address on the chain and represents the transaction address on the blockchain

txTime indicating transaction time, with timestamp indicating to the nearest second

Examples are as follows:

note that:

the json data format defines the interface between the system and the account book, and all types of transaction data are transmitted through the interface.

And step S2, creating a cross-domain model, generating model copyright through a block chain intelligent contract, and giving a user integral.

The required conditions of the step are as follows: the normal running state of the application system; the distributed blockchain ledger service operates normally.

The required equipment includes: at least a blockchain ledger server.

After the user passes CA authentication, a model is created in the platform, and the process of creating the model is a process of solidifying the actual combat experience of the user and is also an authoring process. The system records the copyright of the initial model through an intelligent contract.

In the embodiment of the present invention, the model copyright content is: model ID, affiliated unit, creator name, local creation time, release to knowledge sharing time, model value (integral), model logic, copyright registration, infringement monitoring.

And step S3, sharing the cross-domain model to other users through the blockchain intelligent contract, and giving reward points to the users.

The conditions required in the step comprise: the normal running state of the application system; the distributed blockchain ledger service operates normally.

In the platform, the user shares the model of oneself to other users through block chain intelligent contract to reach the effect of intelligence sharing, the model platform of sharing out can give certain point and exist in the personal account as the reward, and the user can exchange other model knowledge through the point.

Further, referring to fig. 2, after step S3, the following steps are further included: model knowledge sharing, including: a user learns a sharing model through the pictures and texts of the intelligent contract and gives a credit reward to a sharer; the user clones the sharing model to the local through the intelligent block chain contract and gives credit compensation to the creator.

It should be noted that the conditions required for model knowledge sharing in this step include: the application system is in a normal operation state; the distributed blockchain ledger service operates normally.

Specifically, after the model is shared out, the platform provides two operation behaviors to make the model value appear, which are respectively: the user learns the sharing model through the intelligent contract pictures and texts, gives credit reward to the sharer, clones the sharing model to the local through the block chain intelligent contract, and gives credit reward to the creator.

The user learns the sharing model through the intelligent contract pictures and texts and gives the sharer a reward. The platform provides a mode of viewing the image-text details of the model and provides a way for a user to learn the logic of the model on line, a learner can give a certain point reward to a sharer personal account book to the model sharer, and meanwhile, the equivalent points are deducted from the points of the learner account.

The user clones the sharing model to the local through the intelligent block chain contract and gives credit compensation to the creator. The platform provides a sharing model cloning function, a user consumes the equivalent value points of the model to clone the sharing model to the local, so that a cloner has model operation right and model modification right, and meanwhile, the sharer accounts book is increased by the same amount of points.

And step S4, the cross-domain model runs to record the computing resources, data resources and intelligence resources provided by other cities through a block chain intelligent contract, and credit remuneration is given to the model sharer.

Specifically, the cross-domain model operation is a cooperative operation result of two different unit models in two regions. When the model runs through the platform, other units share the model and can automatically operate, the account book automatically records the name of the shared resource, the unit to which the shared resource belongs, the shared user, the shared resource quantity and effective collision data through a block chain intelligent contract, and the equivalent points are stored in the account book of the sharer as the reward, and meanwhile, the equivalent points are deducted from the personal account book of the model operator.

The conditions required in the step comprise: the application system is in a normal operation state; the distributed block chain account book is in a normal running state.

Specifically, the user carries out sharing model canceling operation through the platform, the canceling sharing model is off-shelf on the platform, the authority of checking image-text details and showing cloned value is not provided, and meanwhile, the distributed account book carries out model chaining down through a block chain intelligent contract and deducts the operation of canceling equivalent point deduction of a sharer.

According to the cross-domain model multi-party transaction credible and ledging method, a block chain technology is used as a solution, and a credible distributed accounting method and specification of the cross-domain model transaction are realized. The method and the standard for the model copyright, the method and the standard for the model value quantification, the model operation resource value quantification and the model knowledge sharing value quantification are realized. By adopting the method and the device, model exchange can be realized between different areas under a trustable environment, and the environment of intelligent transaction of users is guaranteed. The invention realizes the copyright of the model knowledge, ensures the rights and interests of user creation, creates the environment of user model creation and further stimulates the power of user model creation. The invention realizes the value sharing of model knowledge, enables users to obtain equivalent value benefits, and stimulates the sharing of user model knowledge, so that the knowledge is disclosed for other users to learn and grow, thereby achieving virtuous circle and mutually sharing the model knowledge. The invention realizes the quantification of the value of the model operation resources, mainly quantifies the computing resources and data resources consumed by the support operation of the cooperators, and gives value consideration to the cooperators, thereby promoting the sharing of the user model.
